Hi

I'm working on some midi thing in python. I had a hard time finding a 
decent library. In the past I used PySeq alot, but that's tricky to 
install and seems un-maintained. So I settled for pygame, and it's going 
ok. However:

1) In PySeq I created inports and outports that were visible for 
instance in qjackctl. Is that possible in pygame (currently I just 
connect to the right client from python)? Why would I prefer one over 
way over the other?

2) If I unplug the connected client or press ctrl-c (my preferred way of 
exiting my programs) I get:

PortMidi call failed...
   PortMidi: `Bad pointer'
type ENTER...

How can I exit a pygame program cleanly without getting errors?

3) One of the things I'd like to do I automatically connect to any 
client that shows up while the program is running and *gracefully handle 
it* if clients disappear while the program is running. I imagine the 
first is a matter of scanning for clients every now and then, but right 
now I get the error mentioned in 2) if I pull the plug on a device that 
my program is connected to. Any ideas how to handle this?

Any feedback is greatly appreciated!
